That means a single STM32G473CBT6 can handle current sensing on a three-phase motor driver (six ADC channels), monitor a handful of analog inputs, and drive multiple set-point voltages or analog control signals without external converter ICs. The peripherals list includes a true random number generator (TRNG), brown-out detect and reset, DMA, PWM, and a full set of watchdog timers — all standard for the G4 series but worth noting if the design requires hardware entropy or failsafe power monitoring without an external supervisor. ## Connectivity and interface set — USB, CAN, QSPI, and more The communication peripherals cover CANbus, I2C, IrDA, LINbus, QSPI, SAI, SPI, UART/USART, and USB. The QSPI interface is useful for connecting external serial Flash or PSRAM for data logging or OTA staging, while the CANbus and LINbus support automotive or industrial fieldbus nodes. USB connectivity is present, answering a common search check for this part.","metaTitle":"STM32G473CBT6 STM32G4 ARM Cortex-M4 MCU, 170 MHz","metaDescription":"STM32G473CBT6 32-bit ARM Cortex-M4 MCU at 170 MHz with 128 KB Flash, 128K x 8 RAM, 20x12b ADC, 7x12b DAC, USB, CAN.
